chain rivet tool

I have just purchased a 520 conversion kit for my bike. I know that I need a tool for cutting and re-riveting my new chain. I have found a lot of these tools but since I was planning on adding to my tool collection, I was trying to see if anyone new a good one that I could purchase. I have seen many of them and I was wondering wich one is the best or wich ones out there work well and can be expected to last a long time. If you could please let me know what you have and/or wich ones work the best. Thank you for your time.
